Electric Field and Current Density Characteristic of Contaminated Solid Insulator

The performance of an insulator may degrade over a time period. One of the main factor is due to presence of contamination on the insulator which leads to flashover, corona and damages the insulator. This study focuses on overhead XLPE cables used in distribution system with voltage rated 33kV. The contaminants are varied in order to study the behaviour of electric field and current density of the XLPE insulator. Contaminant used in this study is sodium chloride, lead and rain water. Quickfield software was used to draw and simulate the contaminated cable. The electrical conductivity of cable and contamination was used to represent every layer of the drawing. From the result produce, analysis on the electric field and current density of a contaminated and non-contaminated insulator was made. Analysis shows that the contaminated insulator has higher electrical field and current density compared to non-contaminated insulator. When the electrical conductivity is high, the electric field is the lowest and the current density is the highest in the insulator. Whereas, the XLPE insulator with sodium chloride contamination has the highest current density followed by rain water and lead because the conductivity of sodium chloride is the highest. The electric field strength of lead is the highest followed by rain water and sodium chloride.

On the Influence of Molecular Structure on the Conductivity of Electrolyte Solutions – Sodium Chloride in Dioxane–Water Mixtures

AbstractTheoretical calculations of the conductivity of sodium chloride in water+1,4-dioxane mixtures are presented and compared with experimental measurements. The method of direct correlation force in the framework of the interionic theory is used for the calculation of transport properties in connection with the associative mean spherical approximation (AMSA). The effective interactions between ions in solutions are derived with the help of Monte Carlo calculations on the Born–Oppenheimer level. This work is based on earlier studies on structure of dioxane+water mixtures and the solvation of ions in it.

Thermal Conductivity of NaCl Embedded in Randomly Distributed Porous-Glass Channels

Our earlier experimental data on the thermal conductivity of porous glass and of the porous glass + NaCl composite in the temperature interval 25–300 K are analyzed from a different standpoint. It is shown that the thermal conductivity of sodium chloride filling randomly arranged nanochannels in porous glass behaves exactly like that of a strongly disordered crystalline system and can be described in terms of Einstein’s model of the thermal conductivity of solids.

Conductivity of Sodium Chloride in Water + 1,4-Dioxane Mixtures from 5 to 35°C II. Concentrated Solution

Conductivity data of sodium chloride in binary mixtures of water and 1,4-dioxanefrom 5 to 35°C were measured, covering an electrolyte concentration range upto the limit of solubility in the solvent mixtures and up to 5 mol-dm−3 inpure water. Data analysis is based on the mean spherical approximation (MSA).Comparison is made with the data representation by the empirical Casteel-Amisequation. The association constants of the MSA are compared with those fromchemical model calculations at low concentrations (lcCM).

Conductivity of Sodium Chloride in Water + 1,4- Dioxane Mixtures at Temperatures from 5 to 35°C I. Dilute Solutions

The molar and single-ion conductivities of dilute solutions of sodium chloride (C<0.01 mol-dm−3) in binary mixtures of 1,4-dioxane with water were measured covering a broad solvent composition range at temperatures from 5 to 35°C. Accurate viscosity and permittivity data were determined for the organic solvent system. Evaluation of the limiting molar conductivity Λ∞, ionic conductivities.Λ + ∞ , and Λ − ∞ , and the association constant K A is based on the chemical model of electrolyte solutions, including short-range forces.
